Poly 60, borax and algea

Why not just enjoy the sparkle?

Why not, indeed!

I've noticed that using DE in my sand filter and running the Blue Dolphin regularly has made my water really sparkle, too. But that's CLEARLY removing particulate matter...

I commented when I posted "the great tetraborate experiment" that the water did seem to be so clear that it sparkled!

don't know why but others have also commented on my water and referred to the 'sparkle".

I suspect it might be the algaestatic properties keeping the water clear since it significantly reduced my chlorine demand.

I've noticed the same "sparkle". We really need to quantify this, I wish I had a turbidity meter, we'd determine if indeed the turbidity goes down (hence it also serves as a floc agent) or if the "sparkle" effect is from elsewhere.

Or perhaps the turbidity goes down becase the borates are inhibiting nascent algae faster than chlorine can kill it, thus keeping the water clearer?
